.Be' it knownthat I, EDWARD GWVHITA RE, a citizen of the United States, and a'resident of VVellsVille, in the county of Columbiana and Stateof Ohio, have invented anew and Improved Heater, of which the followingiis a full, clear, [and exact'description, This invention relates to improvements in heaters, and more particularly to domestic heaters for hot water, steamor vapor use, but primarily for heating water, an-object of the invention being, to provide a heater of the character stated-- which 'c'anbe easily and conveniently taken apart and thoroughly cleaned and assembled without danger of leakage after'assemblagefi; 1 r

A- further ob'ect is to provide a heater of the character stated composed of inner tubes,

surroundedby larger concentric tubes forming an annular water space, and radial tubes fixed to the inner concentricitube, and arranged in spiral form with improved larrangement of burner, whereby the heat is obstructed by the radial tubesat a multiplicity of points to insure a rapid heating of the water.

A further object is to provide a heater ofh the character stated with an improved con struction and arrangement of burner whereby all of the heat units areutilized and a maximum of efficiency had. i

With these and other objects' n view, the:

invention consists in certain novel features of construction and :combinations, and .arrangement of parts, as will be moreifully hereinafter described and pointed out in theclaim. j i

In the accompanying drawings- Figure 1 is a view in vertical longitudina section illustrating my improved boiler.

Figure 2 is a top plan view.

Figure 3 is a fragmentary View in vertical section of the upper portion of the heater taken at right angles to Figure 1.

Figure 4: is a view similar to Figure 3 of the lower portion of the heater.

The Figures 3 and 4 are taken in section on the line indicated by the arrows in the Figures 2 and 5.

Figure 5 is a view in horizontal section on the line 55, of Figure 1. V

I Figure 6 is a fragmentary View in section illustrating a modification.

are located inthe water space screwed into threaded sockets 8 in the head 2. The lowerfends ofzthe, rods 7 project through openings'9 in basel and have nuts Cupped 10 screwed onto their lower ends.

washers llwithpacking rings-12 therein are interposed between the nuts10 and the surface of base 1 "so that when: the nuts 10 are screwed home there is no possibility of leak-f The base l is formedwithaninlet water passage 15 communicating with the water space 14 and having a; coupling nipple 16' projecting thereto forthel attachmentof a;

The head 2 'hasa central heat outlet 19, which is preferably inclinedor flared so as to give the maximum of draft, and thebase; 1 is in the: form'of a ring so that its :open, center: communicates with the interior of 1" tube 5.- As this basefl may restdirectly on a support, openings20 are provided in the wall thereof for the free circulation of 1 air toa'id combustion-m a water outlet passage 17 withwhich a nipp1e18-communi-v cates for attachment to a water outlet pipe JThe tube;5-;isprovidedwith aseries ofj ra-,.

. dial-,watertu bes 2 1.- These water-tubes'are, fixed in openings'in the tube 5 -in,a;ny. ap-' 7 proved 'Inanner, but preferably by weld ng so as to insure tight joints. The tubes 21 are in a spiral series, forming a spiral path through the tube 5 for the heat or products of combustion which are supplied by my improved burner 22. This burner 22 is mounted centrally in the base 1 and has an annular gas space 23 with a ring cap 24 thereon secured preferably by screws 25 and having burner orifices 26 in its opposite faces so that the flame is directed in small jets both inwardly and outwardly and upwardly. The outwardly discharging jets are directed against the inner face of the tube 5 while the inner jets impinge against the tubes 21 and the heat from both series of jets is-directed in a'spiral path through the tube 5 to insure the heating of all the surfaces and a rapid heating of the water in the water space 14 and tubes 21.

The burner 23 may be secured in the base in various ways.

I have illustrated a simple form of construction in which a pipe 27 projects through an opening 28 in the wall of the base and is screwed into the burner 23 at its inner end, and at its outer end has an enlarged Bunsen coup-ling member 29 screwed thereon. A sleeve 30 may be located on pipe 27 against the inner face of the base 1 so that the parts are rigidly coupled.

It is, of course to be understood that the particular manner of securing the burner in the base may be varied, but in any case, the burner would be removable and readily taken apart so that it can be effectually cleaned as occasion may require.

The Bunsen coupling 29 will supply air to the gas to form the desired mixture, and the auxiliary air, or additional air, will be supplied through the base to give a free burning and insure the maximum utilization of heat units.

In operation, water entering the passage 15 will flow into the water space 14 between the tubes 5 and 6 and as it passes upwardly it will flow back and forth through the tubes 21 and then out through the outlet passage 17. During this passage of the water, the heat will be directed against the inner face of tube 5 and against the outer faces of tubes 21 as the flame and gases are carried in spiral path through the tube 5 and out the outlet 19. This will insure a rapid and efficient heating of the water at a minimum expenditure of fuel, and while I have referredjto gas as the fuel, it isobvious that the invention is not limited to gas, as I may employ any desired fuel either liquid, gas, or vapor. It is, of course, to be understood that my invention is not limited to any particular use, as it is adapted for many uses either for heating water for domestic purposes, or for use in connection with radiators for heating purposes.

In Figure 6 I illustrate a modification showing a single gasket X on which both tubes 5 and 6 may be supported, instead of the double gasket construction illustrated in the other forms, and it is to be understood that this single gasket construction is adaptable for both heads.

I would also have it understood that while I have illustrated a particular form of burner for the water heater, would have it understood that the invention is not limited thereto as it is obvious that steam or other fluid might be employed for heating the water. 7

It will be noted that my improved heater can be readily taken apart, cleaned and reassembled, without requiring skilled labor, and that its original cost will be reasonable and the results attained highly satisfactory.

The heater may, of course, be constructed of any suitable material as for example, brass, copper or steel, and may be made in any sizes to suit the trade.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precis details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the I claim:

A water heater, comprising a ring-shaped base having a water passage therethrough, said passage opening out through the top of the ring, said ring having also a lateral opening opposite the'water passage, a head having a central outlet for the products of appended claim.
